[NFHS] Is there room for judgement on this

[SperlingPE]

This is starting to go in different directions.
This was a spot throw-in following a violation by Team B. The designated spot was off to the side of Team B's basket (in Team A's backcourt).
The foul was committed by a Team B player on a Team A player who was in bounds, prior to the ball being inbounded. The thrower had the ball in his possession and the official had started the 5 second count (the ball was at the disposal of the in-bounder).
